Koskuduk

Koskuduk was a caravanserai on the route across Ustyurt between Khwarazm and the lower Volga. Built of stone around a broad courtyard, it had a fortified entrance, towers and large chambers with domed roofs. The springs of Ushkan lay farther along the route towards Saraychik. Pottery and coins from the caravanserais of Ustyurt attest to the importance of this road in the time of the Golden Horde.
